Vitamin E. Computer model of a molecule of the fat-soluble vitamin E (alpha-tocopherol, the most potent form of tocopherol, C29. H50.O2). The atoms (solid tubes) of this organic molecule are colour- coded: carbon (yellow), hydrogen (grey) and oxygen (red). Vitamin E is absorbed with fats (lipids) in the intestines, and is obtained from nuts such as peanuts and almonds, and vegetable and sunflower oils. It is an antioxidant that can remove harmful free radicals, energetic molecules that can damage cells. It also interacts with vitamin C (ascorbic acid), a water-soluble antioxidant. Small amounts of vitamins are an essential part of a healthy diet.
